About this item
Product details
Castrol® GTX® 5W-30 is a synthetic blend motor oil with a double-action formula proven to clean away the sludge that can block engine oilways* and help prevent new sludge formation.

Sludge can block your engine's vital oilways like cholesterol and if untreated, can rob an engine of its power and ultimately its life. * When tested in engines with a high level of sludge

I always use this oil. I shop around and this was the best price by far. But was only available at this price for online order with curbside pickup. I will not do that again!

My favorite engine oil.
I prefer a blend instead of full synthetic for all of my vehicles. I have been using Castrol for years with no problems.
